摘要：

Anodes of Li4Mn5O12, Li4Ti5O12, and Li2Mn4O9 with a spinel-type structure have been evaluated in room-temperature lithium cells. The cathodes that were selected for this study were the stabilized spinels, Li1.03Mn1.97O4 and LiZn0.025Mn1.95O4, and layered LiCoO2. The electrochemical data demonstrated that Li+ ions will shuttle between two transition-metal host structures (anode and cathode) at a reasonably high voltage with a concomitant change in the oxidation state of the transition metal cations so that the Li+ ions do not reduce to the metallic state at the anode during charge. These cells reduce the safety hazards associated with cells containing metallic-lithium, lithium-alloy, and lithium-carbon anodes.
